Michelin HX MXM for '95 Volvo 850 Turbo Wagon

Can someone tell me if all the tires that Michelin makes for Costco are "private label" or if it was just the X-One or the XMetric in a previous message? What about Michelin's that are sold at Sears or Tire Kingdom? Are they "private label" as well? Is there an indication on the tire if it's a "private label" or how can I tell a "private label" from a standard Michelin tire? Thank you.
